Apr 9 2026 APP 2.0.0-beta40 has been released !

It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more, all will be added to the release notes in the coming hours...

Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

Hello Vincent, how is actually the projection rotary controller in 4 register to understand. When I try different settings, the l-c-registered preview looks strange. 🤔

Well, apparently that is a known bug that shows itself in certain modes. Mabula is aware of it and it's on the fix-list, it should ofcourse rotate while staying in the frame. Thanks for the report!

Hi @minusman & @vincent-mod,

The projection rotate enable you to directly rotate the field of view. Once the data is registered, you can study this behaviour with the l-c-registered image viewer mode 😉

I have solved the bug, the bug would only happen with normal integration (Lanczos, Bicubic etc. data interpolations). If you enabled drizzle it would already work correctly.

Check release notes here:

https://www.astropixelprocessor.com/community/release-information/astro-pixel-processor-1-076-preparing-next-release/

  • FIXED, 4) REGISTER, PROJECTION ROTATE, due to an error in the algebra, the pre-rotation of the projection of the Field Of View (FOV) did not work correctly for regular integration. It did work properly for drizzle integration. The field of view was not properly shown in the integration Field Of View. This is now fixed. First image shows the problem that is fixed, second image shows the correct result after the fix:
Register projection rotate bad
Register projection rotate fixed

 

 

Will try to release this in another Beta today or tomorrow 😉

Mabula

Hello Mabula, hello Vincent. I'll check it out with drizzle settings. Have you seen the strange behavior in the stretch module? I reported it in Preview and save calibrated image errors.
